Well, often I more lazy than you, Lorn! Short term, up to a week, I just seal them up in a ziplock bag without anything extra at all! With martagons, or any that can have a propensity to "sulk" for the first season, I make sure they are in contact with a moist light soil mix, peat or vermiculite, and try to keep them in relative darkness. I just sent some martagon section lilies to a friend in Indiana, and yes, there was condensation in the bag. Again, this is short term, say, a week.
